PDE seminar: "Perturbations of embedded eigenvalues for a magnetic Schrödinger equation", Sara Maad Sasane (Lund)
The study of perturbations that preserve the nature of a part of the spectrum of an
operator is a classical theme in functional analysis. In this talk, I will discuss the
question of persistence of embedded eigenvalues for a magnetic Schrödinger operator
on a cylinder, and show that perturbations for which an embedded eigenvalue persists
has the structure of a manifold.
